Rescued co-pilot from the downed Russian Su-24 jet said there were no visual or radio warnings issued by Turkey.

"There were no warnings. Not via the radio, not visually. There was no contact whatsoever. That's why we were keeping our combat course as usual. You have to understand what the cruising speed of a bomber is compared to an F-16. If they wanted to warn us, they could have shown themselves by heading on a parallel course. But there was nothing. And the rocket hit our tail completely unexpectedly. We didn't even see it in time to take evasive maneuvers."
